Java apachelucene中的多属性查询

下面的程序满足查询，其中title同时包含lucene和action。如果我想搜索一个元组，其中isbn考虑isbn不是唯一的是1234，标题包含Lucene和dummies。lucene是否为此提供了设施

 StandardAnalyzer analyzer = new StandardAnalyzer(Version.LUCENE_40);
 Directory index = new RAMDirectory();

IndexWriterConfig config = new IndexWriterConfig(Version.LUCENE_40, analyzer);

 IndexWriter w = new IndexWriter(index, config);
addDoc(w, "Lucene in Action", "193398817");
 addDoc(w, "Lucene for Dummies", "55320055Z");
 addDoc(w, "Managing Gigabytes", "55063554A");
  addDoc(w, "The Art of Computer Science", "9900333X");
   w.close();

 private static void addDoc(IndexWriter w, String title, String isbn) throws IOException {
Document doc = new Document();
doc.add(new TextField("title", title, Field.Store.YES));
doc.add(new StringField("isbn", isbn, Field.Store.YES));
 w.addDocument(doc);
 } 


String querystr = args.length > 0 ? args[0] : "lucene AND action";
Query q = new QueryParser(Version.LUCENE_40, "title", analyzer).parse(querystr);

在我看来，QueryParser类只用于查询标题字段，因此，为了使查询同时以title和isbn字段为目标，您必须使用multifiedqueryparser类和title:lucene和dummies以及isbn:1234等查询，或者只构建BooleanQuery，这就是您手工从多个TermQuery对象得到的结果

我希望这有帮助
